First Evidence Of Under-Ice Volcanoes In Antarctica
An anonymous reader writes "The first evidence of a volcanic eruption from beneath Antarctica's ice sheet has been discovered by members of the British Antarctic Survey. The volcano on the West Antarctic Ice Sheet began erupting some 2,000 years ago and remains active to this day. Using airborne ice-sounding radar, scientists discovered a layer of ash produced by a 'subglacial' volcano. It extends across an area larger than Wales."
everyone was blaming global warming for the melting of the icecaps...

Then that really is a mighty volcano! What next, a volcano with an area larger than 100 elephants?
There are thousands of volcanoes elsewhere on the globe I don't see why antarctic would be any different. I understand before we never had any proof and that is why it is news but I wouldn't say it is Earth shaking news.
How long before people start claiming these as being the source of the melting ice caps?

If volcanic activity is truly sending the glaciers into the ocean, local warming can have a real and serious effect on global climate.
It's funny, Here in Denmark, we here alot about the potential consequences of global warming, about the millions of refugees it will create.
Noone ever mentions that we'll probably be some of those refugees, Our tallest hill, has a height below 170,9 metres, or 560,6 feet above sealevel.
Time for me to buy that land in south america.
Blah blah sig blah blah blah irony blah blah
Okay, probably not a good thing to post so frequently BUT...
From TFA:
Co-author Professor David Vaughan (BAS) says,"This eruption occurred close to Pine Island Glacier on the West Antarctic Ice Sheet. The flow of this glacier towards the coast has speeded up in recent decades and it may be possible that heat from the volcano has caused some of that acceleration. However, it cannot explain the more widespread thinning of West Antarctic glaciers that together are contributing nearly 0.2mm per year to sea-level rise. This wider change most probably has its origin in warming ocean waters."
What warms the oceans? Global warming is a big buzzword today, and not without merit. I just find it interesting that there may be more possibilities out there than just "OMG we are killing the urf!"
Nature has a role to play in this too, humans weren't around during the ice-age, if we were we would have been blamed for Global Cooling I bet...

My little sister is so stupid she thinks Wales are fish. Duh, Wales are mammals.
One of the possibilities that this opens is that there is life that has been evolving separately from the rest of terrestrial life for millions of years. In theory life could live off the volcanic chemicals just as it does at undersea vents. This could be the really interesting part of the discovery.
Wales is that lump of land attached to the the left hand side of England - not the bottom pointy one, the lump above it and no not that island floating in the sea, that's Ireland.
They're not talking about the large underwater animal spelt "whale".
Why's Wales always used as a random country for the purposes of size comparison? I sense a thesis coming on.
For those on the other side of the pond, the area of Wales is about that of New Jersey.
Actually, given that they've located an area of possibly steaming ash and dust, maybe they just found New Jersey by accident.

must be me, but my first thought was "wow! what a splendid Bond villain hideout that would make!"
:-)
ice on, lava below, inaccessible - threat of global destruction by melting the ice caps. now I just need several hundred minions wearing identical surplus overalls and large corridors I can drive my C5s, Mini Mokes and of course the G-Whiz down. Better order a brace of those new TATA mini cars to get with modern times and all the ladies have to wear mini skirts. Damn, better get back to work.
that scandinavia is still rebounding from the loss of its ice sheet in the last ice age
;-)
i don't know the rate, but perhaps the rising seawater and the rising land should counteract each other in scandinavia
i'm not really being that serious, just trying to bring some good cheer to you gloomy nords
intellectual property law is philosophically incoherent. it is your moral duty to ignore it or sabotage it
Yeah, that was exactly my thought when I heard about this. It's even in the same frikkin' part of Antarctica!
Ah, well. At least my house is 30m above sea level...
there was nothing strange in the coordinates provided in the article, but i found this dark spot nearby. Is this the 'evidence' ?
"life is a joke, and someone is laughing at me"
considering themselves scandinavian, and start considering themselves dutch

I remember hearing stuff to suggest the ice on europa was miles thick, but if there's anything alive down there might it support the old Hypthesis?
sound of joke going over your head etc.
This is very bad news (tm).
There is a quite thick layer of soot and ash trapped inside the glacier. At some point when the glacier melts enough, that whole layer becomes visible and thus the reflection of sunlight from the glacier surface diminishes. And the melting speed increases dramatically. To make things worse, the layer will stay there for some time as it is bit warmer than the ice and so it bores small holes where to stay put instead of getting flushed away.
And don't get me started on that active volcano under glacier. How it will react when the weight of the glacier eases rapidly? Possible earthquakes and that means tsunami.
Funny thing, a Finnish author named Risto Isomäki has written a hard scifi book about the subject only couple of years ago. It's called the sands of Sarasvati.
I always wondered how to say "sheep and dirt" in Klingon.

Wales has, for decades, been used in the UK as a standard of measurement, not just of land mass but also of population, annual rain fall, tourist numbers and exports. Every large country's size was measured in 'Wales'es. Popular media, like radio and television have used the 'Wales', mainly in news reports.
"The Americans have invaded Vietnam. This country in south east Asia is 14 times the size of Wales."
"The Falklands have been invaded! These disputed islands, half the size of Wales, have been sought after by the Argentine government for decades."
etc
You mean the country of Wales in the UK?
That's a weird kind of comparison!
But I suppose it's better than World Book Encyclopedia (1967) that kept comparing area to US States. And height comparisons to how many Empire State buildings etc etc.
Don't be apathetic. Procrastinate!
My family very sensibly left Denmark sometime around the 1060s - probably having had to look at one hardwood chair design too many - and settled in the UK. My suggestion is that being a refugee is perfectly OK provided you have a few fast and well armed ships, and politically incorrect attitudes to the people you come to visit. Worked for us and, based on subsequent Danish and British history, can work for you too. Alternatively, imitate the Dutch and build concrete houseboats for the flat, low lying bits.

Would it kill them to show an image of the radar scan, or do they think we're too stupid to understand it? If they're so damn afraid of losing the credit they should just shut up until that's assured and then go public.
Corporate-ized scientists, sheesh...
A plume of ash covered in a thick layer of ice the size of Wales seems slightly more interesting than Wales itself.
Whatever you do, don't go to investigate the volcanoes. Some things are best left undisturbed.
When they uses Wales as an area comparison, is that allowing for all the mountains and valleys? Some say that if you could flatten them all out Wales would more than double in area. Others say that if you could completely flatten Wales, it would be a bloody good idea.
It's true I tell you, feller at work's next door neighbour read it in the paper.
Wuth wong with "21th," you inthenthitiff clod!?
Whales aren't all THAT big...
No gods, no demons, and no masters. Secular Humanism!
Couldn't help it...
This has been known for a long time - that significant underice vulcanism in Antarctica was causing the ice streams. BTW, the much large East Antarctic ice cap is thickening and growing significantly.
And they are indeed mammals. What this has to do with Antarctica, I'm not sure. Oh, did you mean 'whales'? If so then your pronunciation and spelling, rather than your grammar, is off. ;-)
I'm sure she could make a summer blockbuster out of this!

Same thing happened in Red Mars by Kim Stanley Robinson. Good book.
